eGPU on HP Zbook 15 G2

[AnimeLabs]

Issue: I want to buy an Nvidia GeForce GTX 1080ti and I dont want to use my Current Dedicated GPU Anymore because it got shortage because of Humidity. I made it fix by changing the Shorted Component on the GPU but recently I ran into issue with my Dedicated GPU again Now when I Connect Secondary Display to my Laptop via HDMI to DisplayPort. My Laptop Freezes and Even I dont use Secondary Monitor I can't run any application that require a Dedicated GPU lets say for Tekken 7. 

I am thinking of stop using it and buying a used GTX 1080ti with an EXP-GDC Beast IDK if ExpressCard is better or PCIe Version. All I want to know if I will be easily be able to Use eGPU with my Laptop as I have forgotten my Bios Password I can't remember it. But All the necessary Settings were enabled as much as I remember. 

I found a method online to use it on Zbook 15 G1.

Below is the method and here is the link to that forum:

1. Install Win10

2. Attach eGPU but note. The ZBook will fail to boot if the eGPU is detected by the bios. The workaround is to either hotplug the eGPU after BIOS post or set the PTD delay switch on the EXP GDC and the powerdown/powerup the system to activate the PTD delay.

3. Install the AMD eGPU drivers, which will error 12.

4. Fix error 12 by firstly setting BIOS to hybrid graphics mode (should be default), so the iGPU and dGPU are active.

5. Continue to fix error 12 by installing eGPU Setup 1.35 & boot it. Ensure the eGPU is detected, then select:

- PCI compaction->ignore [dGPU] - PCI compaction->Run->iGPU + eGPU

- Video cards->dGPU[off], hit F3 key

- Chainloader->Run

Thereafter boot via Setup 1.35->automated startup (default) whenever you need to use the eGPU.

If this will work for my Zbook 15 G2 without any issue.
